Abstract

A deflection unit for a color television display tube 1 having a field deflection coil 8 and a line deflection coil 7, in which the line deflection coil is formed by two diametrically oppositely positioned coil portions which, on the side adjacent the tube's screen, have a flared end 17 having a profile with a path length 22 which is longer than the path length 23 of the contour of the outer surface of the tube, so that raster defects are smaller than when the profile of the flared ends conforms to the contour of the tube surface.
